Self-assembled clusters of condensed water microdroplets can levitate over a locally heated layer of water. Large clusters form hexagonally ordered (honeycomb) structures similar to colloidal crystals, while small (from one to several dozens of droplets) clusters possess special symmetry properties. Small clusters may demonstrate 4-fold, 5-fold, and 7-fold symmetry which is absent from large clusters and crystals. The symmetry properties of small cluster configurations are universal, i.e., they do not depend on the size of the droplets and details of the interactions between the droplets. The small cluster configurations may be compared with other types of symmetric objects in geometry.
自组装的冷凝水微滴簇可以悬浮在局部加热的水层上方。大的簇形成类似于胶体晶体的六边形有序（蜂窝状）结构，而小的（由一到几十个微滴组成）簇具有特殊的对称性质。小簇可能表现出四重、五重和七重对称性，而大簇和晶体则没有这种对称性。小簇构型的对称性质是普遍的，即它们不依赖于微滴的大小和微滴之间相互作用的细节。小簇构型可以与几何中其他类型的对称物体进行比较。
